Woodward Iron Company Four iron making enterprises each controlling substantial deposits of iron ore coal limestone and dolomite came to dominate the industry These companies were unique in their use of advanced blast furnace plants that smelted iron ore into pig iron Woodward Iron Sloss Sheffield Steel and Iron Company and Thomas Works operated blast furnace plants that produced pig The sodium sulfate was then heated with coal and limestone to form sodium carbonate or soda ash In the late s another method of producing soda ash was devised by Ernest Solvay a Belgian chemical engineer The Solvay method was soon adapted in the United States where it replaced the Leblanc process
